Asymptotic Regularity of Daubechies’ Scaling Functions
Let φN , N ≥ 1, be Daubechies’ scaling function with symbol ( 1+e−iξ 2 )N QN (ξ), and let sp(φN ), 0 < p ≤ ∞, be the corresponding Lp Sobolev exponent. In this paper, we make a sharp estimation of sp(φN ), and we prove that there exists a constant C independent of N such that N − ln |QN (2π/3)| ln 2 − C N ≤ sp(φN ) ≤ N − ln |QN (2π/3)| ln 2 . This answers a question of Cohen and Daubeschies (Re...

متن کاملOn the maximal Lp-regularity of parabolic mixed order systems
We study maximal Lp-regularity for a class of pseudodifferential mixed order systems on a space-time cylinder R×R or X×R, where X is a closed smooth manifold. To this end we construct a calculus of Volterra pseudodifferential operators and characterize the parabolicity of a system by the invertibility of certain associated symbols. A parabolic system is shown to induce isomorphisms between suit...
متن کاملA solution to the problem of Lp−maximal regularity
We give a negative solution to the problem of the Lp-maximal regularity on various classes of Banach spaces including Lq-spaces with 1 < q / = 2 < +∞. Mathematics Subject Classification (1991):47D06, 46B03, 46B52, 46C15
متن کاملNumerical solution of linear control systems using interpolation scaling functions
The current paper proposes a technique for the numerical solution of linear control systems.The method is based on Galerkin method, which uses the interpolating scaling functions. For a highly accurate connection between functions and their derivatives, an operational matrix for the derivatives is established to reduce the problem to a set of algebraic equations. Several test problems are given...
